BRlCK-KILN.

Specification of Letters Patent.

Patented June 25, 190'? Application filed January 29, 1907. Serial No- 354,634:

To all whom it nwty concern:

Be it known that I, HENRY J. WILLIAMS, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Brick-Kilns, of which the following is a specification.

My invention relates to kilns for the burning, drying and cooling of brick or other articles of manufacture made from earth.

My object is. to provide a kiln in which earthenware articles may be burned, dried and cooled in a manner much more reliable, systematic and effective than has heretofore been done or accomplished by any kiln heretofore known or in use.

The mechanism of the kiln and arrangement of parts are such that the workman needs only to become familiar with the mechanism of the kiln and the offices of the various parts and appliances in order to get the results of the invention and secure its advantages.

My purpose is to provide a kiln that will insure the desired results from the various processes through which the article of manufacture passes without depending too much upon the character of the workman, thereby placing the art or trade of the manufacture of brick and other earthenware substances upon a scientific basis, and on a footing with other advanced lines of manufacture.

A further object is to provide a kiln constructed in such a manner as to get the greatest possible amount of heat from the fuel used,.to apply thatheat to the greatest advantage and to shift the heat from one part of the I kiln to another as maybe needed or required and not be obliged to waste the heat generated stack with proper openings into such flue or smoke stack from the said centrally disposed chamber. Each unit of thekiln is provided with a separate and distinct means of providing a draft within and through its space occupied by the ware to be burned, dried or cooled and whereby with the system of valves and air passages a draft or suction may be effected to accomplish the purpose of either forcing hot or warm air through the unit or drawing the same from the unit and substituting cooler or other air in lieu thereof. Air passages from one unit to anotherare provided and when it is desired to carry heat or air of any degree of temperature from one chamber to another,'it is only necessary to open the valves connected with the unit to be effected, and temperature of the adjoining unit will be communicated to it. This process may continue clear down one side or clear around the surface of the kiln taking in each separate unit opening into the central chamber, by closing the valves leading to the intermediate units after the desired atmosphere has completely permeated them and opening the valves connected to the follow ing units in turn as the process of passing from one unit to another is continued. I have inaugurated a fan at one end of the kiln which may be used to further the circulation of air through the different apartments of the kiln, which may be used in an auxiliary capacity with the flue or smoke stack or if it is desired the fan may be idle without interfering in any way with the. functions of the remaining mechanism of the kiln.

In the drawings Figure 1 is a sectional plan view of the kiln taken horizontally on a line near the base or bottom of the apartments or units, Fig. 2 is a sectional plan view of the same taken horizontally on a line near the top of the apartments or units. Fig. 3 is a cross sectional view of the kiln taken 011 the line aa of Fig. 1, Fig. 4 is a longitudinal sectional view of the kiln taken on the line 6-1) of Fig. 1, and Fig. 5 is a side elevation of the kiln.

In a detailed description of my invention 10 indicates an air chamber leading around the outer surface of the kiln to the fan 11 and communicating with the different units of the kiln through air passages 22 regulated by the valves 37 and 20.

The units or apartments 29 in which are stored the brick or other article to be treated, are arranged side by side around the kiln with partitions 19 made of brick or other masonry between each unit or apartment, the said partition 19 being provided with openings 30 from one unit or apartment to the other. Underneath each unit or apartment 29 is a flue 22 leading from the air passage to the central chamber 17 and communicating with the units or apartments 29 by the openings 21. At the top of each unit or apartment 29 and at each end thereof is an air chamber 12 opening into such units or chambers through the valves 13. Between the arch 18 of the units or apartments 29 and the top or finishing wall 38 of the kiln is an air chamber 35 communicating with the units or apartments 29 by means of the small apertures 14. It will be observed that each of these chambers and air passages are connected and are governed by valves so that the passage of air may be effected or obstructed as may best serve the process de sired to be accomplished. Centrally located within the inner chamber 17 is situated the flue or smoke stack 15 which is provided with suitable inlets 16 to complete connections with the outside air thereby completing the draft and furnishing an outlet for smoke.

I desire to call especial attention to the manner of feeding fuel to the kiln and the consequent economy in the saving of fuel. Through the top of finishing wall 38 of the kiln and through the arch 18 reaching to the units or apartments 29 I have provided a system of small holes 14 through which the fuel to be consumed in furnishing the heat to burn the brick or other material is fed, these holes 14 communicating with the overhead flue 35 and in that manner being furnished with the air and oxygen necessary to get the greatest amount of heat from the fuel. A wall 23 encircles the centrally disposed chamber 17 and serves as a partition between the same and the units or apartments 29. The outer wall 24 of the kiln is provided with openings 27 through which the brick or other substance to be treated is conveyed. The valves governing the opening to the inner end of the air passage 22 is regulated by the lifting rod 31.

28 indicates the side walls of the air flue or passage 22 and 32 indicates the arch over the air flue 22, 33 merely indicates the foundation of the kiln, and 34 the bottom wall of the air flue 22.

In the practical use of the kiln the apartments 29 would be properly filled with the brick or other article to be treated and the fire started in one of the apartments, for instance in the unit or apartment situated in one corner of the kiln, the valves 20 will be supposed to be all closed, the valve 20 opening into the air flue 22 will then be opened into the apartment where the fire is first started which fire is maintained by the down draft leading from the air chambers 12, through the flue 35 and the fuel holes 14 thence through the openings 21 into the flue 22 through the valve 20 into the centrally disposed chamber 17 and from thence through the openings 16 into the flue 15 and thence to the outside of the kiln. When it is desired to extend the fire to the apartment adjoining it will be only necessary to close the valve 20 of the air flue 22 in the apartment where the fire is first started then open the valve 20 of the flue 22 connecting with the adjoining apartment, this forces the draft through the openings 30 between the apartments and communicates the fire and heat with the adjoining apartment. In order to heat the next adjoining apartment the valve 20 to the second apartment is then closed and the valve 20 of the third apartment opened and this process continued on down the line and around the kiln as may be desired, fuel being supplied through the openings 14 to the difl'erent apartments as is necessary or may be desired. In case it is desired to use the fan 11 for the purposes of atmospheric distribution, it will be only necessary to open the valves 37 connecting with the air chamber 10, making use of the valves 20 as may be necessary to convey the atmosphere to the units or apartments described.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is In a kiln for burning, drying and cooling brick or other articles of earthenware manu facture, the combination of a number of units or apartments as receptacles for the articles to be treated, arranged side by side around an inner air chamber separated by a wall from such units or apartments, openings in the partitions between the units or apartments for the passage of atmosphere, a continuous air chamber around the outer lower surface of the kiln communicating with a fan andwith an air chamber underneath and connected by openings to each unit or apartment, such air chamber underneath the separate units communicating also with a centrally disposed inner air chamber in which is placed a flue with openings from such flue to such inner chamber, a continuous air chamber around the outer upper surface of the kiln and also the inner upper surface of the different units or apartments, each communicating with the said units, an air chamber between the arch of each unit or apartment and the upper or finishing wall of the kiln, openings or apertures extending through the upper or finishing wall of the kiln and through the arches of the different units or egress for materials to be treated, substanapartments into the open space or chambers tially as set forth. 7 10 of such units or apartments, all air chambers In testimony whereof I affix my signature, and passages leading to the separate units or in presence of two Witnesses.
